To make the inset, measure the distance between point A (middle of the bottom of the bag) to point B (marking of the hinge) and draw a rectangle with one side measuring this length A-B. The width of the rectangle should be between 8 and 10 cm, depending on how roomy you want your bag to be.
En el rectángulo redondeamos un lado corto hacia dentro. La segunda parte de nuestro patrón está.

Now we cut our fabric:2 pieces of every fabric of the basic pattern (2x exterior, 2x interior and 2x batting/interfacing)1 piece of every fabric of the rectangle, placed on the fold of the fabric (1x exterior, 1x interior and 1x interfacing/batting)

1. QUILTINGQuilting is not that hard! Just pin the exterior fabric together with the batting and sew the pattern you want. I made a pattern of diagonal squares. First you draw the pattern with a marker on the batting or with tailors' chalc on the exterior fabric, and then you sew the two layers together. Depending on which side you drew the pattern, you put the gold thread through the needle or on the bobbin.

2. CONSTRUCTIONLet's start with the lining. Line the centre of the bottom of the bag up with the centre of the rectangle, right sides together. Ease in the rounded corners and sew together. Repeat with the other bag piece.The lining is ready!

To finish the bag, we have to attach the bag to the clasp. Depending on the type of clasp, you either glue them together, or you sew them by hand using a backstitch. I used an embroidery thread to sew the pieces together.
